The DivIDE 57c Interface its the most used mass storage device for ZX Spectrum computers. Driven by esxDOS operative system, it can connect any IDE device and use it as a storage media. Of course its fully compatible with all the all the existing DivIDE firmwares (FATWARE, DEFMIR, etc)

With the NMI function you can browse through the files stored on the IDE storage media and load any game in seconds. EsxDOS also brings BASIC extended commands with read/write access to the storage media.

In combination with the +3e ROMs the DivIDE can also work as an IDE interface directly from BASIC. With these roms installed, you are able to access the SD card from within the +3e basic using the regular +3DOS disk commands.
